UNITED STATES ALEXANDER LOVIE, OF ALBANY, NEW YORK.

Specification forming part of Letters Patent No. 130,927, dated August 27, 1872.

To all whom it may concern:

Be it known that I. ALEXANDER Lovin, of the city and county of Albany and State of New York, have invented certain Improvements in Discharge-Pipes and Nozzles for attachingto Fire-Hose, Src., of which thefollowing is a full and exactdescription, reference .being had to the accompanying drawing making a part of thisl specification, in which- Figure 1 is an end view of my spraynoz zle; Fig. 2, a reduced longitudinal section of the pipe and nozzle through the liue w x; Fig. 3, an' end view of the butt 7 of the pipe; and Fig. 4, an end view of my nozzle with a single orifice.

The nature of my invention consists in making the opening through the pipe and nozzle of a rectangular form; and in spray pipes, subdividing the orifice of the nozzle by means of partitions into a number of smaller rectangular openings; the object of it being to increase the range of the stream by overcoming the rotatory motion of water when forcibly discharged from a circular orifice.

A is the body of the pipe, having a square opening through it, tapering in size, as shown. At its lower end it has a screw-butt,77 B, for coupling it to the hose; and at its upper end a screw, C, for attaching the nozzle. D is the nozzle, (whose external form Imake circulan) the openings through it being of the .same form, and of a size to correspond with the ori'- ces of the pipe to which it is attached. For the purpose of spreading the stream to cover a greater extent of surface, and where the stream is'not reoluired'to be carried to a great distance, I divide the orifices of the nozzle by means of the partitions d d into four smaller openings, as shown in Fig. 1; but where it is required to force the stream to a great distance a single square opening, as shown in Fig. 4, should be used.

In discharging water under great pressure from a circular orifice the stream acquires a rapid rotatory motion, which produces a broken and spray-like discharge at a short distance from the nozzle of the pipe, which continues to increase in its dimensions as the distance increases, until the stream is divided into so great a number of particles that the discharging force is no longer able to sustain it, thereby destroying, in a great measure, the effect due to the impelling force. This destructive effect, though not entirely overcome in my improvement, is remedied to such a degree that a solid stream is maintained to a much greater distance than can be obtained with a round discharge ofthe same area, and its effectiveness is thereby greatly increased.

It will be readily seen that my improved nozzles maybe applied to discharge-pipes with round bodies; but, as a much greater effect is produced by the increased length of the square opening, I prefer to construct it as herein shown and described.

I claim as my invention- `1. A discharge-nozzle for iirehose when constructed with a rectangular disch arge-ori-v tice, as and for the purposes herein specified.

2. For the purpose set forth, a dischargenozzle with a rectangular orifice divided by the partitions d d, as herein described.

3. The combination of the nozzle D, having one or more'rectangular openings, with the pipe A, when constructed as and for the purpose set forth.
